Hello, please help. I don't know how to fix this error or even what it means.
Are you connecting to an iOS device? Extensions do not work on iOS devices.
Yes I am using an iOS device, thanks for helping out.
It does not work on iOS. Unlike Android, where you can use extensions, Apple restricts uses of apps, so we still cannot use extensions like the Look extension. Try to use an Android device instead. I recategorized the category to App Inventor for iOS.
Thanks so much again!
